What can we say about the '92 49ers, led by QB Steve Young and coach George Seifert, they were as dynamic as the Montana and Walsh-led 49ers of the 1980s. Looking at the numbers, they had great marks in point differential and turnover margin. They also had eight blowout wins and eight straight victories to close out the regular season. The only failing effort was the home loss to the eventual-champion Cowboys in the NFC title game.

The 1982 Dolphins reached Super Bowl XVII on the strength of a dominating defense. But when Miami reached the big game two years later, the team had seamlessly morphed into an offensive machine. With the emergence of wide receivers Mark Duper and Mark Clayton and would-be superstar QB Dan Marino, who would set the then league record with 48 TD passes in 1984, this team changed the game. With Marino leading the charge, the '84 Fins were virtually unstoppable. For a while that year, it seemed Dan The Man could do no wrong...until the Dolphins were throttled by the 18-1 49ers in Super Bowl XIX.

There have been only four 15-1 teams in the NFL since the league expanded the regular season to 16 games in 1978. So, the following statement shouldn't be constituted as a slap in the face to the Steel City faithful: The '04 Steelers are the worst 15-win team ever.

With that said, there aren't enough words to describe the balance between the Pittsburgh defense, ranked No. 1 in scoring that season, and the offense, helmed by rookie-QB Ben Roethlisberger. Following a Week 2 loss to Baltimore, Big Ben and the defense ripped off 14 straight victories to finish the regular season. The Steelers were similarly stellar in three telling areas: Turnover margin, blowout wins and 3-0 against playoff teams. And just like the '79 Chargers, Pittsburgh posted easy regular-season wins against the future Super Bowl combatants, New England and Philadelphia, blowing them out in back-to-back weeks.
